Wall construction



March 1, 1938. 1.. w. BRUSSE WALL CONSTRUCTION Filed Feb. 18, 1936 INVENTOR. Lesrcr WBrussc ATTORNEYS Patented Mar. 1, 1938 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to wall constructions, and more particularly to wall constructions embodying a water proof layer or coating.

It is an object of this invention to provide a method in the construction of walls of uniting a water proof coating of bituminous material with a'. coating of concrete plaster.

It as further object of this invention to provide a method of constructing a wall with an inner water proof coating of bituminous material and an exterior coating of concrete plaster.

It is a furtherobject of this invention to provide an improved water proof wall construction for the interior of buildings which possesses the advantage over ordinary constructions of being more flexible and less subject to cracking. I

It is a further object of this invention to pro vide a durable, economical, and water proof wall construction for the exterior of buildings.

Referring to the drawing:

Fig. 1 is a sectional view of a wall construction for the interior of buildings, and

Fig. 2 is a sectional view of a wall construction for the exterior of buildings.

prises as a base or foundation section, a composition board i0 commercially known as sheet roc and consisting of a sheet Illa of compressed gypsum with heavy paper lob attached to both sides. The upper portion of the wall construction comprises in addition to the board Ill a coating H of asphalt,'a coating i2 of asphalt and sand, and a coating l3 of concrete plaster.

The lower portion of such wall construction comprises the asphalt coating H and the asphalt and sand coating l2 of the upper portion, a second coating [4 of asphalt, and a layer of tile I5.

In parts of a building where a tile clad lower portion is not desired, the tilel5 and the coating- I! are omitted and the entire wall finished with the. concrete coating l3.

,The wall construction illustrated in Fig. 2 comprises a foundation or base consisting of' concrete blocks 16 held together by concrete mortar ll. To the face of this foundation is secured three coatings, an asphalt coating I8 corresponding to the coating ii, an asphalt and sand coating l9 corresponding to the coating f2, and a stucco coating 20 consisting essentially of Portland cement and -sand and corresponding to the coating l3. The purpose of the asphalt and sand coatings i 2 and I 9 in the constructions described is to effect the securement to the water proof asphalt coating of the exterior concrete coating which,

The wall construction illustrated in Fig. 1 com-.

when applied in the form of mortar as hereinafter described, will not adhere directly to the asphalt coating. Such coating, when properly proportioned and applied, forms a good bond with the inner asphalt coating and presents a rough, porous surface to which the concrete mortar readily adheres. It does not, however, possess the quality of being entirely water proof, and it cannot as a result be used without the inner coating of asphalt to attain agood construction. In the.construction of the wall section shown in Figs. 1 and 2 the asphalt coatings ii and I8 are applied in the form of asphalt-water emulsions, the coatings I2 and i9 in the form of a 'liquid mixture of sand and asphalt-water emulsion, and the exterior coatings l3 and 20 in the form of mortar. These coatings may be applied by means of a brush or spray, or by means of a trowel, the consistency of the materials being varied in accordance with the method used. I prefer, however, to apply such coatings by means of a spray employing materials of suitable consistency for such purpose. For the water proof coatings II and I8 I have found that an emulsion consisting of asphalt and A water results in a very satisfactory coating and permits of ready application. For the intermediate coatings I l and I9, a mixture of 25 per cent fine sand and '75 per cent asphalt-water emulsion in the proportions of one gallon of asphalt to one-half gallon of water may be used. For the plaster coating l3 and the stucco coating 20, I prefer a mortar containing about one part Portland cement to four parts of sand, the ingredients being mixed with sufficient water to form a mortar capable of being sprayed.

The coatings II and H3 in the constructions illustrated are first applied and allowed to dry, following which the coatings l2 and 19 are applied and allowed to dry. After the coatings l2 and I9 have dried suificiently, the coatings l3 and 20 are applied to form the exterior surfacesv of the walls.

The lower portion of the wall shown in Fig.1 is completed by pressing the tile i 5 into place with a coating of water-asphalt emulsion of the type used in the coating ll applied to their backs, and then grouting the joints between the tile with concrete mortar 2|,

What is claimed is:

1. In a wall construction, the method of unitinga water-proof coating of bituminous material With a coating of concrete plaster, which comprises applying to the coating of bituminous material a coating of bituminous material mix with sand, and applying to the coating of bituminous material and sand a coating of concrete mortar.

2. In a wall construction, the method of uniting a water-proof coating of asphalt with a coating of concrete plaster, which comprises applying tothe coating of asphalt a coating of asphaltwater emulsion and sand, allowing said coating of asphalt-water emulsion and sand to dry, and applying to said last mentioned coating a coating of concrete mortar.

3. A wall construction comprising a layer oi fiber material, a coating of asphalt secured to said layer, a coating of asphalt and sand secured to said first coating, and a coating of concrete plaster secured to said second mentioned coating.

4. A wall construction consisting of a tile clad portion and an unclad portion; said first named portion comprising a layer of fiber" material, a coating of asphalt secured to said layer, a coating of asphalt and sand securedto said first coating, a coating of asphalt secured to said second mentioned coating, and a layer of tile secured to said last mentioned coating; and said second named portion comprising the aforesaid layer and the aforesaid first two mentioned coatings 'of said first portion, and a coating of concrete plaster.

5. A method of preparing a wall for the reception of concrete mortar, which comprises applying to the wall surface a coating of waterasphalt emulsion, allowing said coating to dry, and applying to said first coating a second coat ing of asphalt-water emulsion and sand; and allowing said second coating to dry.

6. A tile covered wall including an inner rigid base, a layer of asphaltic material, a superposed layer of asphaltic material and aggregate, a second layer of asphaltic material, and an outer covering of asphaltic coated tile secured to said second asphaltic layer.

7. The process of producing a waterproofed tile surface upon a rigid base comprising separately applying a coating of asphaltum to said base and to tile sections, applying to the coating on said base a second coating comprising asphaltic material and granular material whereby a roughened wall surface is provided, allowing said coatings to dry and pressing the coated tile into place upon said roughened surface.

8. The process of producing a waterproofed tile surface upon a rigid base comprising separately applying a coating of water-asphalt emulsion to said base and to tile sections, allowing said coating to dry, applying to the coating on said base a coating of water-asphalt emulsion and granular material, allowing said last mentioned coating to dry, and pressing the coated tile into place upon the wall surface so produced.
